Answer:

80

Step-by-step explanation:

If Line PQ is parallel to Line SR, and Line PS is parallel to QR, we know that the two opposite angles would be congruent. Therefore, Angle R is equivalent to Angle P.

Angle R is 80 + D. D is unessential at the moment, seeing as 80 is the needed value for A.
